One of our fave (and hard to find) Mosrite models from the early 70' was the 300. Here is a good article in Vintage Guitar Magazine that covers some of its history and another blog from down under's Tym Guitars - very informative with lots of photos and technical details about the guitar. This seemed to be Semie Moseley's twist on combining a Fender Telecaster with a Gibson SG? We feel this will fit well into our Sidejack family of Mosrite tribute guitars!
